The observatory is being developed by Legends, a sport and entertainment company owned and operated by the Yankees, Dallas Cowboys, and Checketts Partners Investment Fund. The high-powered group is close to signing a 15-year lease with the Port Authority for $875 million.

“In one of the most important buildings in the world, we’ll bring back the most important view in the world,” said Legends CEO Dave Checketts at a press conference yesterday. “The top of this rising phoenix — a three-story observatory — will restore another aspect of the World Trade Center Towers: their phenomenal views.”

With Yankee honcho Hal Steinbrenner and Cowboy scion Jerry Jones Jr. looking on, Checketts said that the tour will become a worldwide destination.

A 60-second elevator ride will take visitors to the 102th floor, where a video presentation will tell the site’s storied history.

The main observation deck and gift shop will be on the 100th floor with a restaurant slated for the 101st floor.

Checketts said that the observatory’s high-tech touches and roving “tour ambassadors” will distinguish it from other famed viewpoints like the top of the Empire State Building.

PA Executive Director Patrick Foye would not disclose the planned admission price but said it would be comparable with those at other major city attractions.
